College. Something that most people, like myself, have to come to grip with. Eventually we all grow up and have to start looking towards leaving behind your family and friends. In the episode Brian is starting to leave for college and his parents don't seem all that upset. When time goes on he later believes his parents to be swingers. This is because when his parents are getting the rooms looked at Brian heres mixed sounds. He thinks that they are swingers because what he hears, from his point of view, sound sexual. making it funny. But when the time comes to take everything from his room hiss parents find a picture. The drawing was of him his little sister Lauren and his parents. Seeing this makes his parents sad and realize that they miss him.
This episode I find to be most related to people who have graduated and are looking towards college. It shows the difficulties that we go through at this moment.
